Title: Loudspeaker apparatus and manufacturing method thereof
Inventor: WATABE TOMOYUKI
IPC: H04R9/04
Filed: 2004-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a loudspeaker apparatus, having a plurality of dampers wherein the adhering strength between a connection member and the dampers arranged on the upper side can be enhanced.  <P>SOLUTION: The loudspeaker apparatus includes the connection member to which a groove is formed, the groove being capable of pooling the prescribed amount of an adhesive. The groove is formed at a position in the vicinity of a lower end of the outer circumferential wall of a cylinder part and formed along the circumferential direction of an outer circumferential wall of the cylinder part. The lower side of the inner circumferential edge of the conducting damper, arranged at the upper side among a plurality of the dampers, is fixed to the connecting member across the adhesive coated into the groove. Further, the adhesive is applied to between the upper side of the inner circumferential edge of the conduction damper and the outer circumferential wall of the cylindrical part. Thus, the conducting damper is fixed to the connecting member, in a state of being clamped between the adhesive applied into the groove and the adhesive applied to the upper face side of the conducting damper. Thus, the adhesive strength between the conducting damper and the connecting member can be enhanced. Then coupling force between the conducting damper and the connecting member is strengthened, and the conducting damper is made less likely to exfoliate from the connecting member. Thus, the limiting value of the withstanding input to the voice coil can be set high.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
